-Adaptive Cruise Control •m.____...,__ _____________ _
The Audi braking guard is active from a speed of approx. 20 mph
(30 km/h) and works within the system limits=>
page 149 even when
the Adaptive Cruise Control is deactivated.
A radar sensor is built into the front of the vehicle=>
page 138,
fig. 132. The system is intended to measure the distance to reflective
surfaces. If a measurement is not possible, the system does not
respond.
When the measurement has been taken, the system can recognize a
possibly hazardous situation, for example, when a vehicle up ahead in
your lane of travel suddenly brakes or when your own vehicle is moving at high speed towards a much s lower vehicle up ahead . As
soon as the system senses that a possible collision w ith the vehicle up
ahead can only be avoided by immediate full brake application or by
an avoidance maneuver, a warning appears.
The system has a default response time to be able to signal before a
collision occurs. This system response time is automatically reduced
if you accelerate actively, for example to join a highway . Braking,
transverse acceleration and the steering ang le can lead to a reduced
system response time . The warning is deactivated if you begin to
overtake with full acceleration.
Th e system can make you aware of two different hazardous situa­
tions:
Distance
T he distance warning is given if the system calculates that there is not
enough distance to the vehicle up ahead a period of more than 5
seconds. If the distance is less than 30 feet (9 meters) at 50 mph (80
km/h) , fo r example, an optic al disp lay comes on in the inst rument
cluster=> fig. 151.
If the vehicle ahead brakes sharply, Audi braking guard cannot he lp
you to avoid a coll is ion, even in the case of an immed iate response.
T ake immediate action to avoid the collision and increase the
distance to the vehicle up ahead.
Speed
If there is a much s lower vehicle moving up ahead in your lane, or if
the vehicle a head brakes sharply, the Audi braking guard calculates
the point from which a collision can only be avo ided by full braking or
by an avo idance maneuver. If a warn ing does sound, a possible co lli­
sion with the vehicle in front can only be avoided through an evasive
maneuver or by braking.
The warn ing is given in two stages:
• Pre-warning : A visual display appears in the instrument cluste r
and a warning tone sounds .
• Acute warning: If you do not respond to the pre-warning, the
second stage warni ng is given . A quick brake application helps to
direct your attention to the road and traffic situation .
Under heavy braking, the brake assistant=>
page 138 also helps you
benefit from maximum braking effic iency.
& WARNING
Inattention can cause collisions, other accidents and serious
personal injuries.
• Always pay close attention to the traffic , even when the Audi
braking guard is switched on. The Audi braking guard provides a
warning but does not brake the car for you. You must apply the
brakes yourself!
• Always keep the safe and legal distance between your vehicle
and vehicles up ahead.
• Audi braking guard works within limits and will not respond
outside the system limits, for example when approaching a
stopped vehicle or stationary obstacle (end of a traffic jam or
vehicle that has broken down in traffic).
• Always remember that the radar sensor for the Audi braking
guard works within defined detection and range limits that may
prevent the proper detection of other vehicles. _,.,

• Always pay careful attention to th e traffic situation and be
ready to intervene and be ready to take complete control when­
ever necessary.
• Refle cti ve surfaces including cr ash barriers or tunnel ent rances
may impair the function of the radar sensor .•

Applies to vehicles : w ith s ide ass ist
Description
The side assist helps you when changing lanes.
AUDr Q7
Fig . 152 Rear
bumper: Position of
radar sensors (not
visible on outside)
Fig . 153 Signal light
on the outside mirror -
driver's side
Side ass ist uses radar sensors (not visible on outside)=> fig. 152 to
help the driver check blind spots, and see what is happening in traffic
behind the vehicle=>
page 156, fig. 155.
Signal lights are built into both outside mirrors=> fig. 153. The s ignal
light on the left outside mirror assists when moving ove r into the left lane and
the signal light on the r ight outside mirror assists when
moving over into the right lane.
Th e sig nal light comes on to tell you that side assist has detected a
vehicle on that side and that the position of this other vehicle should
be taken into account if you were to change lanes. Thi s is called the
informational stage signal =>
page 156. The informationa l stage
signal is designed so that you not ice it only when you are looking in
the outside m irror.
When you activate the turn s ignal and side assist detects a vehicle in
a notable location, the correspo nding signal on the outside mirror
flashes briefly and brightly several times. This is the alert stage
signal =>

& WARNING
• Improper reliance on the side assist system can cause collisions
and seriou s per sonal injury:
- Never rely only on side assist when changing lanes.
- Alway s check rear view mirrors to make sure that it is safe to
change lanes.
• Side assist cannot detect all vehicles under all condition s­
danger of accident!
• Side a ssist cannot detect vehicle s in time to alert you when
they approach from behind at very high speed , or fall drop bac;k
very quickly .
• The radar sensor's
vision can be reduced o r entirely blocked by
rain, snow, and heavy spray . Thi s can result in side a ssist not
adequately detecting vehicles o r, in some cases , not detecting
them at all. Always keep an eye on the direction you are traveling
and the relevant area around the vehicle.
• Plea se note that side assi st indi cates there are approaching
veh icles, or vehicles in your blind spot, only after your vehicle has
reached a driving speed of at lea st 19 mph (30 km/h).
• Side assist signal does not work around tight corners (turning
radius le ss than 328 feet, or 100 m ).
• Side assist is no replacement for the driver's full attention. The
driver alone is respon sible for lane changes and similar driving
maneuvers. Always keep an eye on the direction you are traveling
and the relevant area around the vehicle .

Operation
Side assis t comp ares the di stance and differen ce i n s peed of dete cted
vehicles with the speed of you r vehicle. Whenever the difference in
speed and dis tance is registe red as not able if you were to c hange
lanes, a signa l light appears on the respect ive m irror .
Th e signa l can light up if you are passed by a vehicle or if you are
passing ano ther veh icle.
If you pass anot her vehicle slow ly (difference in speed less than 9
m ph, or 15 km/h), the signal ligh t w ill c ome o n as soo n as the other
vehicle is in your blind spot and is detected by side ass ist . When the
difference i n spee d is greater, the signal light w ill not come on .•
A ppli es to ve h icles : w it h sid e ass ist
Informational and alert stage signals
Side ass ist has two signa l stages:
• the informational stage signa l, and
• the alert stage signal.
Side assist helps you by using the appropr iate signa l stage,
depending on w het her o r no t you have activated the turn signal, and
thus have indicated that you are or are not changing lanes.
Informational stage signal
As long as you have not activated the turn signa l, s ide assist informs
you of detected vehicles that a re reg istered as be ing in a no table loca­
tion if you we re to change lanes. Whenever the detected vehicle's
differen ce i n spee d and dis tance is registe red by s ide ass ist as
notable, the signal light on the respective mir ror produces muted
ill umin ation.
T he br ightness of the i nfo rmat iona l stage sig na l is desig ned not to be
as intense, so t hat it does not inte rfe re with yo ur v iew of the road

you look in the outside ·mirror, you can clearly see the informational
stage signal.
Alert stage signal
When you act ivate the turn signal , and side assist has detected a
vehicle in a notable location on that part icular side, the signal light on
this side mirror flashes brightly. The repeated brief and bright
flashing of the alert stage signal reminds you to carefully check
traffic to the rear in the outside mirror and over your shoulder, so that
you can safely complete the lane change~

Side assist's detection area is designed to cover lanes of standard
width to the left and right of your travel lane, depending on whether
you drive in the center of your lane or closer to the edge.
If you drive in narrow lanes, side assist's detection area may also
include other lanes - especially if you tend to drive on the edge of your
lane => fig . 161. Under these conditions, vehicles can also be
detected that are two lanes away, and side assist then could switch
between the informational and warning stage signals.
When driving in very wide lanes, vehicles in the adjacent lane may not
be detected because they are not inside the detection area .•

display :
Audi side assist not available: sensors blocked
The side assist sensors are built into the rear bumper on the left and
right (not visible on the outside)=>
page 154, fig. 152. To ensure
that you do not adversely affect the way side assist functions, foreign
objects (such as stickers or bicycle racks) should not be attached to
the area on the rear bumper where the sensors are located. If side
assist functions are adversely affected, you will see this message in
the instrument cluster display . Remove anything that may be
blocking the sensors.
If no vehicle is detected for a longer period of time while driving, side
assist will also switch off automatically.
